Versions 1.4.9 and 1.6.2 of Wireshark have been released. According to the developers, the maintenance and security updates address a number of vulnerabilities – some of which are rated as 'highly critical' by Secunia – in the open source, cross-platform network protocol analyser. The vulnerabilities could be exploited by an attacker to, for example, cause a denial-of-service (DoS) or compromise a victim's system.
